Definitions

  • a ring made of a flat flexible material can be used as the seal and still a reliable seal can be achieved.
  • the guide plate prevents folding of the seal between two positions when changing the direction of movement of the building platform relative to the building container.
  • the holder 44 can be removed together with the radiant heater 45 from the receptacle 46.
  • the receptacle 46 is in the form of a rail into which the holder 44 is inserted.
  • the holder 44 can be inserted tool-free into the receptacle 46 and removed from it.
  • An attachment can be done for example via springs, clamps or the like. Structures can be provided in which the holder 44 engages in the receptacle 46.
  • the dimensions of the building material receiving areas 23 and 24 and the metering devices 28 and 29 are matched to one another such that a defined amount of building material is moved in front of the coater 27 during each rotation through 180 ° of the metering device 28 or 29.
  • the chamber 85 is bounded on its sides by side walls 86 and upwardly at the level of the building level 11 separated by a partition plate 87 of the upper portion 40 of the space 10. Down the chamber 85 is bounded by a bottom 88.
  • the bottom 88 has in the area below the container 25 a passage 89 for connection of the carrier device 26 with its drive.
  • outlet openings 90 are provided in an area below the corners of the container. In the illustrated embodiment, two outlet openings 90 are provided below each corner of the container 25. However, a different number of outlet openings may be provided, e.g. can also be provided per corner only one outlet opening.
